TO. ALL WHOM IT MAY CONCERN:

- Be it known that I, SAMUEL E. LOCKWOOD, or" Westbury, in the county ofCayuga, and State. of New York,

- have invented a new and improved Upsetting and Punching-Machine; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use i the same,'reference being had to the accompanying drawings,forming part of this specification.

The object'of this invention is to furnish a machine which shall enableblacksmiths and others to upset wagon-tires or bars of iron or steel,punch holes in the same, or in plates of metal, and also gum saws; andthe invention consists in an arrangement of gripes, by which the tire orother article is held when being upset, and in operating a head-block,which is given a lateral motion by an eccentric for upsetting, punching,and gumming.

saws, as will be hereinafter more fully described.

Figure 1 represents a vertical longitudinal section of the machine,showing parts, the section being through the line 2: a: of-fig. 2.

Figure 2 is a. top or plan view of the same, showing the position of thegripes an'dthe sliding head.

' Similar letters of reference indicate corresponding parts. i p

The moving and operatingparts of this machine are made of iron, steel,or other suitable metal, which parts are supported by a frame of wood oriron, as may be deemed best or most desirable.

A represents the frame. B represents the side-plates, to which theeccentricshaft is attached, and which support the head-blocks of themachine. 0 represents the stationary head-block, and D is the movableheadblock. E is the eccentric, and F is the eccentric-rod, which isattached to the movable head-blocl: D. G is the eccentric-shaft. H is adisk-wheel, which is hung cccentri'cally on the shaft G, to which thelever I is attached, as seen in the drawing: On each of the heads 0 andD there are removable blocks J J,-whose inner. ends are tongued andgrooved, so that they fit and guide each other, as J is moved back andforth on or by the head D.-

On the face of these blocks there are projecting pieces ii, the faces ofwhich are notched or serrated, as seen in the drawing. The blocks J Jare kept in place, when in use, by flanges d cl, on the heads 0 and D,and by .lugs on theirbottom sides, which fit into recesses in the heads,but they are easily removed at any time when not in use. K represent twogripe-wheels with scrrated peripheries hung eccentric-ally to the heads0 and I D, with levers llattached, as seen in fig. 2, by which they areoperated. The pivots onwhich these wheels K K turn areseen at m m.

In upsetting a wagon-tire, (a band or bar or axle of iron or othermetaL) the tire or bar is placed horizonta'lly in the machine betweenthe serrated edges of z'i'and K K, (the head D being slipped back towardthe eccentricE.) The gripe-wheels K K are now turned, so as'to firmlyhold the tire or bar, and the eccentric E is operated by the lever'I,forcing the head D thereby toward the stationary head 0, andupsettingthe tire or bar in the operation. The tire or bar is, ofeourse,'heatecl to a proper temperature 'before'being' put in themachine.

n is a punch, which is attached'to the sliding head D by a. square headon itsend, setting in a recess, or in any other suitable manner. 0 is ablock, whichis attached to the sides or frame of the machine, through'which the punch'n passes, it being a guide forthe punch. P .is a die,which is dovetailed into ,the machine,

-r S, all constructed and arranged as described, for the purposesspecified.

and isremovable (as is also the punch) in the usual manner withpunching-machines. 1 isia hole back of the die, through which thepunchings or chips drop to the floor. S is a recess or aperture, whichpasses horizontally throughthe machine, in which the tire-or bar orarticle to be punched is placed, (against t.he die.)

, The punches and dies may be changed at pleasure, and dilferent sizesand'shapes used, which change'as to the general arrangement. of

shape would be especially necessary in gumming saws, where the operationwould be the same as in punching The punch in all cases would beoperated by the eccentric and lever I, asin upsetting. -In punching andgumming saws theblocks J J would be removed, and the gripe-wheels K Kalso, if desired.

Having-thus described my invention, I claim asnew, and desire to secureby Letters Patent- The improved machine herein described, copsisting ofthe stationary head-block O, sliding head-blocl D, connecting-rod F,eccentric E upon shaft G, eccentric-disk H, with its lever I, stationaryblocks J, and sliding block J, having serrated projections z'z", toothedeccentric-wheels k, and punch '22, dieblock O, and openings SAMUEL E.LOOKWOOD.
